Bloys.

An early and detailed birds-eye town-view of Bloys. From the greatest publication in this genre!. The Civitates was compiled and written by George Braun, Canon of Cologne Cathedral. Braun gathered together vast amounts of information and draft plans to produce over 500 city views/maps published in six parts between 1572 and 1617.
Most of these engravings were made by Simon Novellanus and Frans Hogenberg, many after drawings by Joris Hoefnagel.
COMMENTARY BY BRAUN (on verso): "Blois is a splendid and famous city in France, situated on the Loire, partly in the plain, partly on hills. Here are very many springs and wells, as a result of which many famous personalities who are ill come here on the advice of their doctors in order to recover their health. This has led to some royal and princely children being brought up here, so that Blois is sometimes called a royal city.
Outside the town there is a very beautiful castle, the royal palace, from which one looks down into the broad pastures and river meadows."

This view shows the city of Blois from the southeast, from a viewpoint above Faubourg de Vienne overlooking the Loire. The château de Blois with its great central court (3) dates from the 13th century. The Renaissance Francis I wing is notable for its loggia façade and octagonal stair tower. Today the 17th century cathedral of Saint-Louis occupies what was previously the site of the church of Saint-Solenne. The former Benedictine abbey of Saint-Laumer was renamed the church of Saint-Nicolas. In the 16th century Blois was the residence of princes and kings, such as Louis XII and Francis I.
The plate was engraved after a woodcut in Belleforest's Cosmography Universell, Paris, 1575.
